Title: Formation of multi-component thin film
Inventor: OZAKI YUUZOU
IPC: H01C7/04
Filed: 1978-06-30
Abstract: PURPOSE:To obtain a thin film having a desired resistance value easily by compounding a plural number of materials(particularly Co and Mn) in a desired proportion and then by forming it into a thin film on a base plate by sputtering method. CONSTITUTION:A pulsral number of materials(preferably Co and Mn) which are to be formed into a thin film are compounded in advance in a desired proportion to obtain a metal material. The proportion is changed according to predetermined resistance values bexause the resistance value of thin film formed varies with different component proportions. The metal material is used as a target for sputtering method to form a thin film on the surface of a base plate. The control of the proportion of cimponents in this method is much easier than the conventional methods in  which the proportion of components in two materials is constantly controlled by  changing the respective evaporating temperatures of two evaporating sources so as  to equalize their vapor pressures. This method is suitable for the manufacture of  thermistor materials for thermistor and bolometer which serve as thermal detection  elements.

Title: Liquid fuel combustor
Inventor: TAKAHASHI MUTSUHIKO
IPC: F23D11/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To start stabilized combustion operation quickly by providing a nozzle for ejecting gasified fuel upward disposed oppositely to the upper surface of a burner seat and a U-turn type vaporizer heater fixed along the opposite sides of the vaporizer. SOLUTION: Upon starting operation, power supply to a vaporizer heater 44 is started. Consequently, a vaporizer 27 is heated efficiently from the opposite sides by means of a vaporizer heater 44 and the temperature of the vaporizer 27 is increased quickly to the vaporization point of kerosene. Since the load on the vaporizer heater 44, i.e., the object to be heated, is only the vaporizing part of kerosene in the vaporizer 27, heat generated from the heater 44 is consumed extremely effectively for bringing the temperature of the vaporizing part to the vaporization point of kerosene and the temperature of the vaporizing part is brought quickly to the vaporization point of kerosene.  When the vaporizer 27 can be heated only with the heat obtained from a heat receiving fins 41 as the time elapses, power supply to the vaporizer heater 44 is interrupted and combustion operation can be started quickly.

Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To disperse and receive the impact force of a vessel and absorb it by fixing a corrugated fender having fixed parts on both edge parts of a circular body, which is formed of a flexible material, to the front surface of a mooring quay wall by rivets. SOLUTION: A fender having fixed parts 2, 2' on both edge parts of a semicircular sectional body 1 formed of a flexible material, such as rubber, soft synthetic resin or the like is formed so as to have a corrugated form. One or two pieces of the thus-formed fenders are arranged on the front surface 3 of a mooring quay wall so that the mountain parts are never superposed, and the fixed parts 2, 2' are fixed by fixtures 4 such as rivets. Since the fender has a corrugated form, the contact surface with a vessel is increased, the time difference of contact is caused, and the impact force can be weakened by this portion. Further, the mountain part of the fender is formed of a curved part, and changeable to any form, the impact force can be further more weakened.

Inventor: TAKAHASHI YUTAKA
IPC: H03K17/78
Filed: 1983-05-09
Abstract: PURPOSE:To prevent other circuit elements from being destroyed even if a constant current element is destroyed by connecting a current limit element and the constant current element in series with the circuits elements to be destroyed if a forward current becomes a prescribed value or over. CONSTITUTION:n-Set of light emitting diodes 20-1-20-n, a resistor 22 and an MOSFET24 are connected in series.

The value of a resistor R is set so that the current flowing to the light emitting diodes is smaller than the forward maximum current of each light emitting diode if the source and drain terminals of the MOSFET24 are short-circuited. Since the current flowing to the light emitting diodes is limited even if the MOSFET is destroyed, the destruction of the light emitting diodes is prevented.

Title: Optical memory medium
Inventor: SATO YOSHIO
IPC: G11B7/24
Filed: 1986-04-09
Abstract: PURPOSE:To rewrite the memory contents at high speed by forming the layers of a recording material which records the information corresponding to the intensity of a laser beam when the material receives the laser beam and is heated and a good conductor which is easy to generate eddy current when impressed with a magnetic flux. CONSTITUTION:The medium is made amorphous when heated to a temp. higher than the transformation temp. theta1 and then quenched, and made crystalline when kept at a temp. between the transformation temps. theta2 and theta1. Namely, the medium has two crystal phases at ordinary temp. Consequently, the physical and electrical characteristics such as the spectral reflectance of an electromagnetic wave such as laser beam, electrical resistivity, refractive index, degree of polarization, and transmissivity differ between both phases, and information can be recorded by utilizing the characteristic change. The amorphous phase hardly conducts electricity, and is almost insulated. Since an eddy current is not generated even when a magnetic flux change is provided to the amorphous substance, a good conductor film is furnished close to the recording medium. When the disk 10 is rotated clockwise under such conditions, the magnetic flux passing through the conductor is changed, an eddy current is formed, hence heat is generated, and the recording medium is heated.
